Its in between and ARF and a Kit. It has CNC cut foam cores for all flying surfaces and even the fuselage. They supply balsa sheeting that you apply very easily with M77 spray adhesive. When finished it is completely balsa covered, which makes it very strong, ding proof, yet very light. With some light sanding it looks as smooth as any fully sheeted balsa plane that the pros fly. The great thing is there is no fragile balsa frame that takes hours to build and seconds to smash to bits. You cover with heat shrink and it looks A. You can paint it and looks A+ class.
